Hi All, I have been on the FML for about one month now and I have read about "ferret digging grounds" Could someone describe these to me. I walk my boys on leashes and the have an outdoor cage which I put them in for an hour or so, but never thought about putting them in all day. I'm curious about these digging grounds? I would appreciate any information. Thanks, Lisa and her boys Sneak & Chamois [Posted in FML issue 2721]
